Patent DE-19654791-A1 (DE)
Title: Semiconductor component manufacturing method for film and substrate separation
Inventor: MATSUNO YOSHINORI
IPC: H01L21/78
Filed: 1996-12-31
Abstract: The method involves using film which is deposited on a substrate over a separating layer and an etchant which is filled into the holes to remove the separating layer. The semiconductor film is removed from the substrate, while the etching rate is increased by an etchant admixture. Preferably the separating layer is of silicon oxide and the film of silicon. The substrate contains a P-type impurity, whose concentration is typically 1E17 cm to power of -3, or less. The surface of the separated film may be further etched to reduce it by 0.1 to 0.4 microns.
Patent DE-19654862-A1 (DE)
Inventor: STRASER ANDREAS DIPL ING
IPC: B61F5/42
Filed: 1996-12-04
Abstract: A multiple-unit railway vehicle comprises three wagons (1, 2, 3), adjacent wagons being interconnected in articulated manner by a single coupling joint (8) and each wagon (1, 2, 3) being mounted only on a two-axle bogie. In the region of the respective coupling joint (8), and optionally on the bogies (4), are actuator elements (10, 11) which are used to influence the inflection angle between the longitudinal shafts of the wagons. In order to be able to control the inflection angle such that, when travelling over a curved track line section, the wagons adopt a position relative to one another which corresponds at least largely to the respective track line section in the static rest position of the railway vehicle, the track section path during travel is determined for a line section which currently lies between the first and last bogies and the desired position is determined therefrom, the actuator arrangement (10, 11) counteracting at least one overshoot or undershoot above or below the desired value.

Title: Optical bench for determining particle size and distribution in sample
Inventor: IGUSHI TATSUO
IPC: G01N15/02
Filed: 1997-01-08
Abstract: An optical bench for determining particle size/distribution in a sample substance (5) by measuring the scatter/refraction of a light beam (2) has a Fraunhofer pinhole screen (15) to facilitate alignment of the light source (1) and detector surface (16) with respect to the bend axis. The detector surface (16) has a quadrantal pattern of areas sensitive to the light (10) scattered by the sample (5) and a central sensor registers the light (11) which remains undeflected for complete intensity analysis via the multiplexer (8) and CPU (9). Four separate sensors surrounding the central sensor of the surface (16) enable beam centralisation when the pinhole screen (15) is inserted (position V) and the surface (16) moved to equalise the four intensity signals.

IPC: G06F17/30
Filed: 1997-07-04
Abstract: The system handles data of a documentation containing a group of data objects, which are processed in a data processing system. A group of links is associated with the kind of the documentation to be prepared. Each link defines possible source instances, from which a connection can go out, by device of a generic instruction, and assignment instructions of source instances of certain structure elements, which are available in the data objects, to respectively one target instance of a structure element of another or the same data object. Each link is stored in a memory in such way, that the respective generic instruction is stored in connection with the respective instruction for the assignment of a corresponding target instance.  The data objects of the documentation are searched for source instances appearing in the processed link, and each discovered source instance of the existing data objects is associated according to the link with a target instance, as far as it is available within the data object group. The address of the respective target instance is stored in the data object group in connection with the source instance, to improve the possibilities of navigation of an user.

Patent DE-19747737-A1 (DE)
Title: Device for determining fullness of fluid esp. oil level in vehicle
Inventor: WALDE TIM
IPC: F01M11/12
Filed: 1997-10-29
Abstract: The device has two temperature dependent resistors. These are arranged relative to the surface of the fluid such that they extend axially over the range of the change in fullness expected. A defined quantity of heat is fed via a heating current to the sensor resistor. The heating or cooling of the sensor resistor is used as a measurement for the degree of fullness.  The sensor resistor is heated by a regulator to an upper defined temperature threshold (T2). The oil temperature is measured via a second resistor i.e. a temperature probe resistor. After reaching the temperature threshold and setting the heat current in an analyser the time is detected until the sensor resistor is cooled to the lower temperature threshold.
